Lugar not (quite) most bipartisan

What’s a good way to measure the neutrality of a bipartisanship ranking put together by former Sen. Richard Lugar?

How about the fact that Lugar himself ranked only 24th out of 227 senators who have served since 1993.

“It shows at least it was an objective survey,” Lugar said on C-SPAN’s "Washington Journal" on Monday when asked if he was disappointed he didn’t come in first.

The index — created by the Lugar Center and the McCourt School of Public Policy at Georgetown University — measures how often lawmakers cosponsored bills authored by a member from the other party, and how often they attracted cosponsors from the other party to their own legislation.

The index was first released last year to rank current members of Congress. Lugar recently expanded the list to rank former senators, and will soon add former House members.
